Christmas Day seems to be the time for artists to release music new, old, and just plain weird, and legendary producer Timbaland was not about to miss out on the celebration. After hinting that his latest mixtape would include an unreleased track from the late, great Aaliyah, whom the producer collaborated with on some of her biggest hits, including “Are You That Somebody†and “Try Again,â€Â Timbaland delivered the goods on Christmas when he dropped his mixtape, King Stays King. The Aaliyah track, “Shakin,†is second on the mixtape, which also features appearances from Young Thug, Migos, Rich Homie Quan, Tink, and 2 Chainz. According to Billboard, the project is meant to be a preview of Timbaland’s full-length Textbook Timbo, which is due out next year.
